50 Kopecks North Russia - Chaikovskiy Government

The Chaikovskiy Government — formally the Supreme Administration of the Northern Region — was a short-lived anti-Bolshevik authority established at Arkhangelsk in August 1918 under Allied protection, named for the Socialist-Revolutionary leader Nikolai Chaikovskiy. It issued its own currency out of practical necessity: Bolshevik rubles were politically unacceptable, and Allied military scrip was inadequate for civilian use. These small-denomination notes were essential for daily transactions in a region that remained economically functional despite being encircled by civil war.

The government itself collapsed in 1920 following Allied withdrawal, and the notes quickly became worthless. Survival in any condition is reasonable but not abundant.
